Abstract
A portable cell balancing repair tool for correcting cell-to-cell voltage imbalances. The tool defines a voltage set-point that identifies a desired voltage that the cells will be charged to for the cell-to-cell voltage balancing. The tool selects a cell to be balanced, measures the voltage of the selected cell and determines if the measured voltage is less than the voltage set-point. The tool charges the selected cell with a charging current for a predetermined period of time, and then determines if the voltage of the selected cell is greater than the voltage set-point after the time expires. The tool continues charging the selected cell at the charging current if the measured voltage is not greater than the voltage set-point, and determines if the charging current was at the minimum charging current if the measured voltage of the selected cell is greater than the voltage set-point.
